Post-translational modifications result in protein heterogeneity. The densitometry scan demonstrates the purified human cell expressed protein exists in multiple glycoforms, which differ according to their level of post-translational modification.
The triangle indicates theoretical pI and MW of the protein.

A sample of ab84062 without carrier protein was reduced and alkylated and focused on a 3-10 IPG strip then run on a 4 20% Tris-HCl 2D gel. Approximately 40 μg of protein was loaded; Gel was stained using Deep Purple™. The spot train indicates the presence of multiple glycoforms. Spots within the spot train were cut from the gel and identified as Cripto1/CRIPTO (Fc Chimera) by protein mass fingerprinting.

Lane 1 – MW markers; Lane 2 – ab84062; Lane 3 – ab84062 treated with PNGase F to remove potential N linked glycans; Lane 4 – ab84062 treated with a glycosidase cocktail to remove potential N- and O-linked glycans. Approximately 5 μg of protein was loaded per lane; Gel was stained using Coomassie.
Drop in MW after treatment with PNGase F indicates the presence of N-linked glycans. A further drop in MW after treatment with the glycosidase cocktail indicates the presence of O-linked glycans. Additional bands in lane 3 and lane 4 are glycosidase enzymes.

General info
Function
GPI-anchored cell membrane protein involved in Nodal signaling. Cell-associated CRIPTO acts as a Nodal coreceptor in cis. Shedding of CRIPTO by TMEM8A modulates Nodal signaling by allowing soluble CRIPTO to act as a Nodal coreceptor on other cells (PubMed : 27881714). Could play a role in the determination of the epiblastic cells that subsequently give rise to the mesoderm (PubMed : 11909953).
Sequence similarities
Belongs to the EGF-CFC (Cripto-1/FRL1/Cryptic) family.
Post-translational modifications
The GPI-anchor is attached to the protein in the endoplasmic reticulum and serves to target the protein to the cell surface. There, it is processed by GPI processing phospholipase A2 (TMEM8A), removing an acyl-chain at the sn-2 position of GPI and releasing CRIPTO as a lysophosphatidylinositol-bearing form, which is further cleaved by phospholipase D (GPLD1) into a soluble form.
